Last June I purchased a Dead Air Sandman L. At the same time my buddy purchased an Omega because that is what our dealer had on hand. Fast forward to this past Saturday. We had a chance to finally get our rifles out and shoot them with the new suppressors we had purchased. I had a consistent .4 mil POI shift downwards at 100 yards. It did not effect windage.

My buddy's Omega had no shift in POI at all. In fact he was able to shoot his tightest group ever on his new 6.5 Creed.

We shot them next at 300 yards and his shift was .1 mils downward.

I have a sample size of one when it comes to the Omega. Is anyone else experiencing similar results in POI shift? I can pick an Omega at a great price and may consider doing so if I can get a better sample size with the same results.

I get a consistent mil low and mil left. On my lightweight rifle it is more.

What are the two guns? A bull barrel will flex less than a straight profile, the straight less than the government profile, and lightweight barrels flex quite a bit.

With AR rifles I have a feeling a part of the shift is upper to lower receiver fit.

I would imagine that POI shift or lack of it is due to both the weight of the can on the barrel and its effect on how the barrel flexes when firing. Putting my TBAC suppressor on various rifles causes POI shifts with all of them.

I'm shooting a RPR in 6.5 Creedmoor and my buddy is shooting a Savage Stealth also in 6.5 Creedmoor.

My 16" SCAR 17s with Omega exhibits no POI shift

Roughly 0.25 MOA POI shift with an Omega on my .308 R700. Similar on 5R Tactical in .300 WM.

On my rifle with the Kreiger heavy varmint I get about .3 mil shift, but on my new Broughton comp contour I can't even tell if it's the Omega or the wind - maybe even just me. I don't think it shifts at all. Certainly no noticeable difference at 100yds.

It's always completely repeatable which makes me happy.
